Question
Write the following as rational numbers in their standard forms.
240÷(-840)
240÷(-840)
✓
Answer
Given, $240 \div(-840)=\frac{240}{-840}$
$\because$ HCF of 240 and $840=120$
On dividing numerator and denominator by their HCF, we get $\frac{240 \div 120}{-840 \div 120}=\frac{2}{-7}$
In standard form,
$\frac{2}{-7} \times \frac{(-1)}{(-1)}=\frac{-2}{7}$
